GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 398,452, dated February 26, 1889. Application filed $epten1her 10, 1888- Serial No. 284,972. (No model.)

To 6!, whom, it may concern:

Be it known that I, \VILLIAM N. RUMELY, of La Porte, La Porte county, Indiana, have invented certain new and useful Improvements in Governors, of which the followingis a specification.

This invention pertains to governors 'lor steam-engines and other motors, and the improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure l is a front elevation of a steam-engine governor embodying my improvements; Fig. 2, a front elevation, upon. a somewhat onlarged scale, of the vertical spindle thereof with. its attached head-work, and showing also the bevel-gear and washer at the foot of the spindle in vertical diametrical section; Fig. 3, a front elevation, on an enlarged scale, of one of the governor-armsshown detached; and Fig. 4: a side elevation of the same.

In the drawings, A indicates an ordinary governor-valve structure; B, the usual housing above the same to support the governor mechanism; 0, the usual pulley, by which the governor is driven through the medium of the ordinary horizontal shaft bevel-geared to the vertical spindle of the governor; D, the vertical spindle journaled in the housing and carrying the centrifugal mechanism at its upper end and bevel-geared at its lower end to the horizontal shaft of the governor; E, the valve-stem sliding axially in the vertical spindle and connected at its lower end with the governor-valve and arranged to be operated upon at its upper end by the centrifugal mechanism; F, the ordinary spring-and-lever mechanism for pressing the valve-stem and valve upward into a position corresponding with the open condition of the governor-valve, and serving, also, as a means for adjusting the centripetal force of the governor, and consequently the speed of the motor, and serving, also, in operating the valve by hand when used as a sawyers valve; G, the bevelgear upon the foot of the vertical spindle by means of which that spindle is driven from the usual bevel-gear of the horizontal shaft; H, a washer interposed between the hub of the beve1-gear G and the foot of the housingbearing in which is journaled the vertical spindle, the exterior diameter of this washer being less than that of the hub of the bevel gear G; J, an upwardly-projecting rim formed upon the hub of the bevel-gear J, exterior to the washer, and forming a cup upon the bevelthe same horizontal planeone to each side of the axis of the spindle; M, a pair of spring abutments carried by the head of the vertical spindle radial to the pivots L and presenting their faces at an angle to the horizontal; N, the governor-weights; O, the governorarms pivoted at their lower ends to the pivots L, and bearing the governor-weights at their outer upper ends, these two arms crossing each other and lying closely side by side, each arm being curved sidewise, as shown in Fig. 4:, so that the contiguous faces of the arms at the crossing are in the plane of the axis of the vertical spindle, the centers of the two governor-weights being also in this plane; P, a lug upon the inner face of each of the governor-arms and projecting therefrom, and serving as stops to engage the inner edges of the governor arms and limit the inward movement of the governor-weights, the position of the governorweights,when these stops engage, corresponding with the full-open position of the governorwalve; Q, cams projecting downwardly one from each governorarmand engaging the top of the valvesteni E, the valve-stem at its top being enlarged to form a seat for these cams,which thus lie alongside each other on the head of the valve-stein; R, an adj usting-serewone for each governorarm screwed through a lug on the governorarm, the axis of such screw being substantially at right angles to the face of the appropriate spring abutment M; S, a spiral springerie for each governor-arm-interposed between the screw R and spring abutment M; and T, the outwardly-projecting lugs-one for each governor-arun-which support the screws R.

The normal position of the parts is as indicated. in Figs. 1 and 2, the governor-arms bearing against the lugs P and being pressed against the same by the springs S. Under the influence of centrifugal motion the governor-weights move outwardly and down wardly, the governor-arms moving away from the lugs P, and the cams Q acting downwardly upon the valve-stem and properly affecting the position of the valve. The movement of the governor-weights, as the effect of the centrifugal motion, is resisted by the springs S, which thus furnish the centripetal force, which force is adjusted by means of the screws R. The spring of the speed-changing mechanism F, tending to elevate the valvestem, serves also, of course, in furnishing centripetal power. In the operation of the governor there is a rubbing movement of the cams Q upon the top of the valve-stem, and

the surfaces are to be kept properly lubricated. The bearing of the vertical spindle dle D in the housing is also to be kept properly lubricated in the usual manner, and the lubricant running down this bearing finds its way to the cup J, where it is retained and lubricates the thrust-bearing at the foot of the Vertical bearing, thus preventing the upward wearing of the gear J under the upward strains due to the running of the bevel-gears. I claim as my invention 1. In a governor, the combination, substantially as set forth, with the governor-valve and stem and the spindle carrying the centrifugal mechanism, of a pair of horizon tal pivots, L, carried by the head of said vertical spindle, a pair of governor-arms, O, pivoted to said pivots and crossing each other above the planes of said pivots, and provided with cams Q, engaging the top of said valve stem, weights upon the governor-arms, stops to limit the movement of the governor-arms, angularly disposed springs S, engaging spring abutments upon the head of the vertical spindle, and adjusting-screws upon the governorarms between the pivot and weight of said arm.

2. In a governor, the combination, substantially as set forth, with a governor-valve and stem and a spindle carrying the centrifugal mechanism, of the head K, carried by said spindle, pivots L, carried by said head, curved governorarn1s 0, carried by said pivots and carrying weights N, and lying close alongside each other at a point of crossing, and provided with cams Q, engaging the top of said valvestem, and with lugs P, engaging each the opposite arm, and springs acting between said head and arms to furnish centripetal force.
